Description
In the Linux kernel, the following vulnerability has been resolved:
drm/v3d: Reject invalid indirect BO handle in indirect CSD setup
v3d_get_cpu_indirect_csd_params() looks up the indirect buffer object
from a userspace-supplied handle but never checks the result. A bogus
or stale handle makes drm_gem_object_lookup() return NULL, which is
then stored in info->indirect and only dereferenced later when the
indirect CSD job runs, turning a userspace mistake into a NULL pointer
dereference in the kernel.
Bail out with -ENOENT as soon as the lookup fails, so the bad handle is
rejected at submission time.
